Hammond Organ Restoration, Techniques and Suggestions
Certified Foam Free
You will see "CERTIFIED FOAM FREE" in some of the descriptions of our instruments on our Inventory page. You will also see a label on the front of each organ that says "Certified Foam Free" and you may wonder,"what does this mean?"
During the last 9 years of factory B3 and C3 production, foam strips were substituted for felt in the keyboards as a dust inhibitor. However, over the years the cheaper foam can decompose and chemically react with the fine wires that carry the tonal frequencies from the keyboards to the preamp and then on to the Leslie. This does not always happen, but it CAN happen and this is VERY bad. A musician expects to hear all the notes and tones he is playing, not a percentage of the tones that should be heard. What is worse is that the problem only gets worse over time until the organ potentially becomes worthless without major repair and expense.
Keyboard Exchange International, having observed and recognized this issue, is making the effort to remove factory installed foam from each and every organ that we restore! The reason this is important to us and our customers both, is that the foam will never be a future issue in organs purchased or restored by Keyboard Exchange International.
Organs from 1965 to 1974 do tend to sound brighter, crisper, and clearer due to factory refinements. A musician should not need to choose reliability over tonal preferences. Keyboard Exchange International has solved this problem! Consider this when you make a long term investment in a vintage Hammond organ and only buy an instrument that has been certified foam free by a reputable business.

Several of our customers asked us to explain how to maintain their Hammond and Leslie so we scheduled a two day, informal seminar and provided them with some hands on experience and question and answer time. The instructional videos shown on our Hammond Organ Maintenance
page are the result of people asking us to provide specific information. We plan to continue offering information so that our customers will always be well informed and so that everyone interested in Hammond organs and Leslies will be better prepared to help preserve them. We once had as a company slogan "Help Us Save the B3's"......... I think we will start using the slogan again as it now seems more appropriate than ever.
Our thanks to the guys who participated and offered their helpful suggestions and input. We all benefited from the time spend together
